What is OKF
Open Knowledge Format is useful when knowledge needs to stay readable by humans while also being easier for AI agents to scan, route, and retrieve.
OKF uses plain Markdown files with YAML frontmatter so knowledge can stay readable without a special runtime.
A folder of OKF documents can be shipped through Git, a zip archive, or any static file host.
AI agents can scan titles, descriptions, tags, resources, links, and body sections before loading deeper context.
Why OKF matters
Without structure, a knowledge folder becomes another pile of text. OKF adds just enough metadata to identify what each file is, what it describes, where it came from, and how it connects to related concepts.
How OKF works
The frontmatter gives compact structured data. The Markdown body carries the explanation, examples, tables, citations, and links.
